I never got the sense that HWR's actions were from any sense of benevolence even from his own POV.
I think most villains see themselves as the hero of their own story--and I don't think HWR is different. That said, I wasn't really thinking about Loki being the villain and HRW being the hero in this series--just that it has a touch of irony that Loki, in trying to save the multiverse, will bring about the destruction of everything (assuming that Secret Wars follows the comic story a little more closely than Secret Invasion did).
